STUDIES ON TRANSITION METAL PARACYCLOPHANE COMPOUNDS - REACTIONS OF [(M(ETA(6)-C16H16)CL-2)(2)] (M=RU, OS) WITH TERTIARY PHOSPHINES - THE CRYSTAL STRUCTURES OF [RU(ETA(6)-C16H16)CL-2(PPH(3))].CHCL3 AND [RU(ETA(6)-C6H6)CL-2(PPH(3))].2CH(2)CL(2)

摘要

The synthesis of the compound [{Os(eta(6)-C16H16)Cl-2}(2)] is described. The reactions of the compounds [{M(eta(6)-C16H16)Cl-2}(2)] (M = Ru, Os) with tertiary phosphines are investigated inpolar and non-polar solvents. Neutral compounds [M(eta(6)-C16H16)Cl-2(PR(3))] and cationic complexes [M(eta(6)-C16H16)Cl(PR(3))(2)](+)X(-) (X = PF6, BPh(4)) are obtained, respectively. The crystal structure of a representative compound [Ru(eta(6)-C16H16)Cl-2(PPh(3))] has been determined and the structure is compared with that of the simpler analogue [Ru(eta(6)-C6H6)Cl-2(PPh(3))].
